can no longer use my printer

[CyberInfluencer]

I downloaded this
https://pretendprusa.co.uk/index.php?action=downloads;sa=view;down=18

I have the menus and stuff. The BL-Touch just blinks and cannot lower my z-axis

I also loaded the .hex file via USB using my linux laptop. Now when I connect my linux laptop - I see ttyUSB0 but cannot connect to my printer.

Help would be appreciated. Thanks

If the z axis will not lower then your wiring is wrong. Check the white and black cable and the single wire that connects to the z max and stop.  Try connecting at 250000 also.
